Level Switch for Liquids

The series LC-40 level switch for liquids uses a float to activate a micro-switch. The magnetic coupling drives the switch so there is no direct link, requiring a seal, between the process and the instrumentation. This provides a robust measurement that is well suited to severe or corrosive processes.

The installation in the tank can be vertical or horizontal depending on the type of float system used.

The level dead band is variable. That is, the level differential between the high and low switching points.

A robust construction and versatile configuration options make the LC-40 easily adaptable to the many different installation requirements of most industrial processes.

Suitable For

  • Dosing tanks
